Bicycle shoe to pedal cleat shim and mounting

Abstract

An improved bicycle shoe to pedal cleat shim comprises a shim body with mating faces on opposite sides of the shim body, each for mating with another surface, each mating face having two or more shim to shim keying features. There is also a cleat with two or more cleat to shim keying features. There is also a mounting screw with a convex curved seating face and a washer with a substantially matching mating concave curved seating face. The screw has one or more grooves incrementally cut along the length of the thread. The shim has thickness marks adjacent to the screw relief pocket on the shim. There is also a cleat with the cleat to shoe/shim mating face having one or more friction inducing pads that comprise a pocket to allow space for friction material to flow when the cleat is mated to the shoe, shim or another shim.

The invention claimed is: 
     
       1. An improved bicycle shoe to pedal cleat first shim comprising a shim body with mating faces on opposite sides of the shim body, each for mating with another surface, each mating face having a plurality of shim-to-shim-keying-features, wherein the shim-to-shim-keying-features comprise two or more pins offset to the same side of a heel to toe centreline of the first shim on one of the mating faces, wherein the shim-to-shim-keying-features comprise two or more sockets on the other mating face for receiving pins of a second shim, wherein the sockets are to the same side of the heel to toe centreline as the pins of the first shim. 
     
     
       2. A first shim according to  claim 1 , wherein the mating faces are either parallel or angled with respect to each other. 
     
     
       3. A first shim according to  claim 1 , wherein an other surface is capable of mating with each of: a pedal cleat, a bicycle shoe, and another mating surface of the second shim. 
     
     
       4. A first shim according to  claim 1 , wherein the mounting faces further comprise one or more friction inducing pads. 
     
     
       5. A first shim according to  claim 4 , wherein the mounting faces further comprise a non-slip texture on a remaining surface portion of the mating faces. 
     
     
       6. A first shim according to  claim 4 , wherein each friction inducing pad comprises a protrusion above the mating faces. 
     
     
       7. A first shim according to  claim 6 , wherein each friction inducing pad comprises a pocket to allow space for a friction material to flow when the shim is mated to the bicycle shoe, pedal cleat or the second shim. 
     
     
       8. A first shim according to  claim 1 , wherein each of the sockets is one of: a socket through the first shim, back to back sockets or a socket on the other side of one of the pins. 
     
     
       9. A first shim according to  claim 1 , wherein each pin of the first shim is on the same side of the heel to toe centre line, the first shim is stackable on the second shim, and pins of the second shim are able to be received in the sockets. 
     
     
       10. A first shim according to  claim 1 , wherein the first shim is stackable with the second shim, wherein each pin of the first shim is on the opposite side of pins of the second shim and the pins of the second shim are able to be received in the sockets. 
     
     
       11. A first shim according to  claim 1 , wherein each pin of the first shim is positioned in line with a corresponding one of the sockets of the other mating face on the same side of the centreline of the first shim and is connected to the shim body by a narrowed section of material parallel to the mating face. 
     
     
       12. A first shim according to  claim 11 , wherein each pin is removable by breaking the narrowed section of material. 
     
     
       13. A mounting assembly for mounting a bicycle shoe to pedal cleat, comprising a screw with a convex curved seating face and a washer with a substantially matching mating concave curved seating face, and the improved bicycle shoe to pedal cleat shim according to  claim 1 . 
     
     
       14. A mounting assembly according to  claim 13 , wherein a centreline of the concave curved seating face of the washer is offset to a washer centreline, allowing for the washer to be turned in a slot of the cleat permitting greater movement of the cleat whilst maintaining surface area between the washer and a cleat body, and keeping the load force over the centre point of a washer to screw interface. 
     
     
       15. An improved bicycle shoe to pedal cleat mounting cleat comprising a cleat body with a cleat to shim mating face having two or more cleat to shim keying features comprising two or more pins, and the improved bicycle shoe to pedal cleat shim according to  claim 1 . 
     
     
       16. A mounting cleat according to  claim 15 , wherein the keying features of the bicycle shoe to pedal cleat mounting cleat comprise two or more sockets for receiving pins of the shim. 
     
     
       17. An improved bicycle shoe to pedal cleat first shim comprising a shim body with mating faces on opposite sides of the shim body, each for mating with another surface, each mating face having a plurality of shim-to-shim-keying-features, wherein the shim-to-shim-keying-features comprise two or more pins offset to the same side of a heel to toe centreline of the first shim on one of the mating faces, and wherein the shim-to-shim-keying-features comprise two or more sockets on the same mating face as the face with the pins and are for receiving pins of a second shim, wherein the sockets are on the opposite side of the heel to toe centreline as the pins of the first shim. 
     
     
       18. An improved bicycle shoe to pedal cleat first shim comprising a shim body with mating faces on opposite sides of the shim body, each for mating with another surface, each mating face having a plurality of shim-to-shim-keying-features, wherein the shim-to-shim-keying-features comprise two or more pins offset to the same side of a heel to toe centreline of the first shim on one of the mating faces, and wherein the shim-to-shim-keying-features comprise two or more sockets on the other mating face for receiving pins of a second shim, wherein the sockets are spaced symmetrically about the heel to toe centreline of the first shim.
